Description

(54) Inflatable Rescue Rag

one

The invention relates to emergency equipment, namely the design of inflatable life rafts.

Famous inflatable liferaft in which the floating body is made of

flexible material

The disadvantage of this raft is in the duration of its installation in the working position.

The closest to this invention to the technical essence is an inflatable liferaft containing an elastic floating ring-shaped hull with a tubular side, a flexible bottom and a protective canopy equipped with an air balloon, an emergency power supply container and a pump 2.

The disadvantage of such a life raft piles into a low reliability of its installation in the working position when dropping and the difficulty of transportation,

The purpose of the invention is to improve the reliability of the installation of the raft in the working position when dropping and transportability.

For this, the tubular bead is provided with curvilinear linings with rigid brackets and support rods that secure a protective canopy located on either side of the flexible bottom, which is installed freely suspended at the level of the lower edge of the tubular bead,. and made in the form of a row of inflatable tubes in contact with each other, with a waterproof strip at the points of attachment of the flexible bottom to the tubular side.

FIG. 1 schematically depicts the described inflatable. life raft section; in fig. 2 - view A of FIG. one.

The floating body of the raft contains a tubular annular flange 1 n flexible foot 2

Board 1 is attached i is waterproof ring lane 3,. to which, along the contour of the bead 1, the bottom 2 is hermetically attached, freely suspended at the level of the lower edge of the latter. The bottom 2 is made in the form of a series of contiguity with each other inflatable tubes 4.

Channel 5 is attached to the outer and inner sides of the raft, and on the upper and lower parts of the bead there are curvilinear lining in with rigid consoles 7 n support rods 8, On the consoles 7 rods 8 set a protective canopy 9 (with both Bottoms A container 10 of emergency power supply with covers 11 located on both sides is mounted in the bottom 2. On the bottom 2 there are also pumps 1 which connect pipes with sprays 14 by tubes 13 and a compressed air cylinder 15. The latter is piped (Fig. not shown) associated with tubular side The proposed inflatable rescue area works as follows, When the condition of the raft of the cantilever 7 is lowered (not at all), the cannon is 7 and goes horizontally, Javez 9 (above) is folded, Shga19gi 8 is folded inside the w. On the other hand, the side 1 at {shmbles the ring-shaped bottom 2 hangs at the level of the lower edge of the tubular borg 1. At the top of the raft | are installed the rods 8, which raise a part of the canopy 9 for the water drain falling on top of it. If it is necessary to cool the canopy under tropical conditions, the seawater is supplied by pump 12 to the nebulizer 14, Invention Form Inflatable life raft containing an elastic floating ring-shaped hull with a tubular side, a flexible bottom protective canopy equipped with a carrying balloon, emergency supply container And with the pump, about tl and h and and with the fact that, in order to increase the reliability of the installation of the raft in the working position of attachment and transportability, the tubular bead is equipped with curvilinear plates with a gesture Kimi consoles and support rods, supported by a protective canopy, located on both sides of the flexible bottom, which is installed freely suspended at the lower edge of the tubular bead and made in the form of a series of contiguous inflatable tubes, and in places attached to the flexible bottom to the tubular board, a waterproof ring is mounted.
